Yes there is. For example, I've made once some calendar like thing
where you can select a month from a 2 columns menu.

Untested code, but should work:

  GtkWidget *combo;
  GtkListStore *store;
  GtkTreeIter iter;
  GtkCellRenderer *renderer;
  int i;
  char**p;
  char*months[]={"jan","jul","feb","aug","mar","sep","apr","oct","may",
                  "nov","jun","dec",NULL};

  store=gtk_list_store_new(1,G_TYPE_STRING);
  combo=gtk_combo_box_new_with_model(GTK_TREE_MODEL(store));
  renderer=gtk_cell_renderer_text_new();
  gtk_cell_layout_pack_start (GTK_CELL_LAYOUT(combo),renderer,TRUE);
  gtk_cell_layout_set_attributes(GTK_CELL_LAYOUT(combo),renderer,
                                 "text",0,NULL);
  gtk_combo_box_set_wrap_width (GTK_COMBO_BOX (combo),2);

  for(p=months;*p;p++){
    gtk_list_store_append(store,&iter);
    gtk_list_store_set(store,&iter,0,*p,-1);
  }

  gtk_combo_box_set_active(GTK_COMBO_BOX(combo),0);
  g_object_unref(store);

Good luck.
